大方廣佛華嚴經隨疏演義鈔 36.17

36.17

疏「欲觀性空」等者，緣於眼起等是理起，明知色塵中入是事入。二「以契即事之理」下，出所以。唯約事理無礙明所以，於中二：先成上分別事相應入事定而入理定、後「制心即理之事」下成上欲觀性空應入理定而入事定。三「而經文但云」下，出二定得名所以，顯上入正定所對之文由對觀故。四「亦合將根事對於境理以辨無礙」者，結例。謂合有二偈，云「於眼根中入正定，於色起定心不亂，了色無生無有起，性空寂滅無所作。於色塵中入正定，於眼根中三昧起，分別眼性不思議，諸天世人莫能知。」

Regarding the Commentary's statement, '"wishing to contemplate the emptiness of nature," and so forth': since arising at the eye and so on is an arising in terms of principle, one clearly knows that entering in the visible form dust is an entering in terms of phenomena. Second, from 'Because it accords with principle, which is identical to phenomena' onward, it presents the reason. It explains the reason solely in terms of the non-obstruction of phenomena and principle, within which there are two parts: first, establishing the above [point that] differentiating phenomenal characteristics should enter phenomenal samādhi, yet enters samādhi of principle; and second, from 'restraining the mind in phenomena, which are identical to principle' onward, establishing the above [point that] wishing to contemplate the emptiness of nature should enter samādhi of principle, yet enters phenomenal samādhi. Third, from 'Yet the sūtra text merely says' onward, it presents the reason why the two samādhis obtain their names, showing that the text corresponding to the above entering into right samādhi is due to its correspondence with the contemplation. Fourth, 'One should also correlate the phenomenal eye organ with the noumenal sense object to distinguish non-obstruction': this concludes by drawing a parallel. This means there should be two verses, saying: 'Entering right samādhi within the eye organ, / Arising from samādhi in visible form with a mind undistracted, / One understands that visible form is unproduced and has no arising, / Its nature is empty, quiescent, and without activity. / Entering right samādhi within visible form dust, / Samādhi arises within the eye organ; / One differentiates the eye's nature as inconceivable, / Such that gods and worldly people cannot know it.'
